Olympics Wi-Fi Police. They seek unauthorized wifi signals & shut them down… If you bring your own Wi-Fi hotspot to the Olympics this is how they find you.
Portable directional antenna for tracing signal transmitters and interference sources. Due to its small size and low weight, the Active Directional Antenna R&S HE200 is ideal for portable use.
In conjunction with portable receivers, it allows signal transmitters and interference sources to be reliably detected and localized. The direction is found by orienting the antenna towards the maximum signal level.
The wide frequency range is covered by three frequencyband-optimized antenna modules. The linearly polarized directional antennas have cardioid radiation patterns so that a constant DF accuracy is attained over the entire frequency range.
